Specification of Letters Patent.

Patented Dec. 4, 1906.

Application filed January 9. 1906. Serial No. 295.233-

To all whom it may concern: v

Be it known that I, LEWIS O. CAMERON, a citizen of the United States of America, re-, siding at Bellevue,. in the county of Allegheny and State of Pennsylvania, have in-L vented certainnew and useful Improvements 1J1 Heaters, of which the following is a specification, reference being had therein to the accompanying drawings. This invention relates to certainnew and, useful improvements in heaters; and the invention relates more particularly to a heater wherein gas is employed as a-fuel or heating medium.

The primary ob'ect of my invention is to provide a portable heater which can be mounted beneath the floor of a building or; suspended therefrom, whereby the space above the floor will be thoroughly-heated. In this connection my improved heater is adapted to be used in the cellar of a building for heating the first-floorcompartments thereof, but may be readily constructed within a suitable casing whereby the second-floor compartments may be easily heated.

To this end I have constructed a simple and inexpensive heater which will utilize all the heat units and produce considerable heat from a minimum expenditure of fuel. The heater is constructed whereby it can be easily and quickly disassembled and in its entirety forms a compact and portable heater.

With the above and other objects in view, which will more readily appear as the nature of the invention is better understood, the

' same consists in the novel construction, combmation, and arran ement of parts to be hereinafter more ful y described and then specifically pointed out in the claim,'and, referring to the drawings accompanying this application, like numerals of reference designate correspondinglparts throughout the several views, in Whic Figure 1 is a front elevation of my improved heater, partly broken away, Fig. 2 is a vertical sectional view of the same with the perforated hood of the j et-casing omitted. Fig. 3 1s a transverse sectional view taken on the line a: w of Fig. 1. Fig. 4 is a plan of a 'et-casing used in connection with the heater.

ig. 5 is a plan of a register or radiator forming the top of my improved heater, and Fig. 6 is a vertical sectional view of a hood used in connection with the heater.

To put my invention into practice, I construct my improved heater of two frustoconical casings 1 and 2, the lower end of the casing 2 being flared, as at 3, to snugly fit upon the casing 1. The casing 1 near its bottom is prov1ded with a transversely-arran ed gas-inlet pipe 4, the-one end of which is p ugged or capped, as at '5. the pipe 4 is a gas-jet 6, and'mounted upon said jet is a spider-plate 7, which supports a cylindrical jet-casing 8. The jet-casing extends upwardly to about midway within the casing 1 and has its upper end partially closed by a perforatedplate 9, while a similar plate 10 is located centrally within the casing 8 as a horizontal partition. Obviously wire gauze may be used in lieu of the perforated plates 9 and 10.

Adjacent to the upper end of the casing 1 the inner walls are provided with brackets l 1, which support a plurality of brackets 12, carrying an inverted-cone-shaped hood 14, having tapering sides 15 and 16, the sides 16 being of a greater taper than the sides 15. The depending end of the hood 14 extends within close proximity to the jet-casing 8, and the tapering sides 16 of said hood are adapted to deflect the heated air, w 'le the tapering Centrally of- I sides 15 of the hood, together with the side walls of the casing 1, are adapted to deflect the heated air downwardly, thus causing a thorough circulation of the air around the jet-casing before its admission to the compartments to be heated.

The casin 1 upon its one side is provided with a suita 1e opening 17, having a hinged door 18, which may be locked in a closed position b a conventional form of latch 19, carried y the handle 20 of the door. The casing 1 is also provided with a handle 21, whereby the casing may be easily carried, together with its appurtenant parts.

The casing 2 extends into a rectangular metallic frame 22, which is mounted in the floor of a compartment, asbestos 23 or like material being used to line the rectangular frame to prevent the heated air from injuring or distorting the floor through which it passes. The rectangular frame 22 is adapted to support a register 24 of a conventional form,which is provided with openings through which the heated air from the heater passes into the compartment.

- To support the heater in proper relation to ICC the floor in connection with which it is used, I have provided the upper edgesof the cas ing 1 with .eyelets 25, to which supportingwires may be attached to brace and support the heater-casings 1 and 2 in proper position relative to the floor through which the heated air passes.

In order to protect the gas-flame of the jet 6 in rough and windy weather, I have devised a perforated hood 26, which is mounted over the upper end of the jet-casing 8, this hood being adapted to house the flame within the casing and prevent the walls of the casing 1 from fusing or becoming excessively heated.

In operation cold air is adapted to pass upwardly through the bottom of the heater, and when contacting with the heated sides of the jet-casing 8 and the hood 14 the cold air becomes heated, especiall since the tapering sides 15 of the hood 14 file and deflect the cold air, while the heated air is deflected and baffled by the tapering sides 16 of the hood 14. The air when heated passes upwardly" between the hood 14 and the outer walls 'of the heater through the register or radiator 24 to the compartment to be heated.

To facilitate combustion, the casing 1 and door 18 are provided wi h openings 27 for the admission of air.

o preferably construct .my improved heater and scope of the invention.

of galvanized sheet iron'or steel, whereb a light and durable structure will be provi ed capable of being used for a long period of time.

Such changes in the construction and op- 3 5 eration of my improved heater as are permissible by t e ap ended claim may be resorted to without eparting from the spirit What I claim, and desire to secure by Let- 4o ters Patent, is-

In a heater, the combination with a suitable gas-supply-pipe and a register, of a twopart frusto-cone-shaped casing connectin with said register, a gas-jet mounted in sai casing and connecting with said supplyzpipe, a cylindrical jet-casing carried by ,sai et,

perforated plates mounted in said casing,. an

inverted-cone-shapedhood suspended in said heater-easing above said jet-casing, aiperforated hood mounted upon said jet-casing, said heater-casing havingopenings formed therein, and a hinged door olosing. one of said openings, substantially as described.

In testimony whereof I afiix my signature in the-presence of two witnesses. LEWIS O. CAMERON.
